Science includes biology, physics, chemistry, biochemistry, biophysics, and various subspecialties like physiology, anatomy, organic chemistry, histology etc.
Math should count as a science, but I asked a dentist who does admissions at UCSF the other day and she said math isn't counted as a science at their school. I don't know if it is the same for AADSAS or not.
I know psychology is definitely not supposed to be counted as a science, but there is some confusion over bio-based psych classes like neuropsychology...
I spoke with an AADSAS representative about this a while ago. Math is listed as Other Science, and you are to use your own judgment to decide if a psych class can be Other Science (eg. neuroscience classes are basically all bio)
